Welcome to our forum.
Congratulations to you Jons,Glad you are finally on the winning side of this. This thread should serve as a lesson to others about how important it is to keep your spa in good order. It’s a long story, but some time ago I had shut my waterfall off and inadvertently left it off. Sure enough, I had some bio-film build up behind the waterfall. My situation wasn’t as bad as yours, but I learned a very valuable lesson in how much work it is to get rid of this stuff.

I've heard differing opinions.
I finally KO'd the paper mold I drained the week long Ahh-Some out of the tub after work yesterday, then filled, drained, and refiled. I added a cup of bleach and let the water temp come up overnight. I did what I believe was my 6 or 7th Ahh-Some treatment this morning starting at 530. An hour later I added 1/2 gallon of bleach and let it run for an hour. Then I drained, filled, drained again. I forced water into all the jets via a garden hose nozzle and saw ZERO evidence of paper mold. I removed all the jets, placed them in a bucket filled with water and vinegar, let them soak, then washed them with clean water. I also heated up some water, mixed it with vinegar and cleaned the tub thoroughly. Chem geek, I did my best to clean the sides of the tub at the water line twice a day to help minimize the problem you spoke of. I sort of succeeded as I didn't have any hard gunk to remove however I did have a small gummy type layer of stuff to remove at the water line which the hot water/vinegar easily removed.I plan on doing one more purge around the last week of December, about 5 weeks away. I'm off that week and IF anything is coming back hopefully I'll notice it by then and be able to quickly squelch it before it gets out of hand. One last time I want say thanks to everybody for helping me fight and conquer the demon beast known as paper mold. I don't think I would have succeeded without you. Also thanks to the people who run this forum, without you none of this would be possible.
Leave it at least partially open. When your circ. pump is running, you want water coming out of your waterfall. With no water coming out of your waterfall, you will get a build up of bio-film. And as you’ve seen in this thread, it is a whole lot of work to get rid of it.

We have been closing the waterfall valve but leaving a little trickle coming out, which was what one of the Jacuzzi technicians advised us to do. Maybe I'll start leaving it open with a little bit more flow, after what you've shared. I guess there is no downside, or wear & tear issue, since the circ pump is running anyways, right?Thanks again
